There is considerable interest in the use of methanol, ethanol, and other polar molecules as cosolvents in super-critical extraction processes, wherein the cosolvent methanol would enhance the ability of a solvent gas, carbon dioxide, e.g., to solubilize a liquid- or solid-phase species. The three-phase liquid-liquid-vapor (11g) phase equilibrium behavior of the mixture carbon dioxide + ethane + methanol was experimentally studied. The boundaries of the three-phase 11g region in pressure-temperature space are delineated. Compositions and molar volumes of the two liquid phases and the vapor phase along the 288.15 and 298.15 K isotherms are reported.
